CLASSIFICATION OF HEART DISEASE RISK WITH MULTILAYER PERCEPTRON: A MACHINE LEARNING APPROACH

Arief Rahman Hakim — 2024-12-30

This research explores the integration of Principal Component Analysis (PCA) with Support Vector Machine (SVM) classification to identify the key factors influencing customer satisfaction using questionnaire data. Leveraging SVM's effectiveness in questionnaire-based classification and PCA's feature reduction capabilities, the study examines the impact of PCA on model performance. From a dataset comprising responses from 100 participants regarding product quality, price, and service level, PCA was employed to reduce the questionnaire features to three components. Results revealed Product Quality as the most significant factor affecting Customer Satisfaction, while Service Level exhibited the lowest influence. Comparative analysis of SVM models with and without PCA integration demonstrated improved performance metrics, including reduced error rates and enhanced accuracy. PCA mitigated overfitting risks, enhancing model generalization and interpretability. The findings underscore the practical significance of PCA in optimizing SVM classification models for customer satisfaction analysis. Future research may focus on optimal component selection and the robustness of PCA-SVM models across diverse domains, advancing machine learning applications in real-world scenarios.

IMPLEMENTATION OF THE SELECTION SORT ALGORITHM IN THE APPLICATION OF WEB-BASED NETWORK INSTALLATION ORDERING AND REPAIR SERVICE OFFERINGS AT PT ARYA PERSADA UTAMA

Damara Al Zura — 2025-01-30

Along with the rapid advancement of internet technology and the ease of access to the use of this technology today, it raises the idea of its utilization in helping project managers who in this case represent the owner (owner) in order to supervise and control the projects under their auspices.

(owner) in order to be able to supervise and control the projects under his auspices. In terms of working time, project managers have limitations, especially for supervising and controlling because the projects they handle are often more than 1 (one), whose activity times run simultaneously. So that the existing information system can be stored and easily accessed at any time by the project owner (owner), a web server is needed that can accommodate the data and information that has been done. Information in the existing database is not only intended for the project owner (owner) but can also be accessed by other parties who have a certain interest in the project. The availability of an integrated project performance report system and project work status information, can facilitate and speed up the reporting process to the project owner (owner). Development of the latest project management information system using the web-based Selection Sort Algorithm Method which is one of the methods in project management that is widely used, especially for companies engaged in software development. This application can provide real-time data or information through the Dashboard page provided by the manager. All activity history both problems and solutions during project implementation are recorded in this application through the reports provided, so that it can be a reference for planning and implementing similar projects later.

The Application for Recognition The Cultural Of The Mandailing Tribe In North Sumatra Using Adobe Flash

Ira Wardani Hasibuan — 2024-12-28

Indonesia is a country with diverse ethnicties and culture. Along with the development of the times, information technology is also growing and people’s lifestyle are increasingly modern. In connection with the development of people’s lifestyle, in fact ethnicity and culture are starting to fade away. Even the interest of the younger generation to get the tribes and cultures that exits is starting to wane. Therefore , there is a need for action to increase the interest of the younger generation to get to know the diversity of ethnicities and cultures in Indonesia by utilizing information. The purpose of this research is to build and introduction to the culture of the Mandailing tribe using adobe flash. The information collections technique that the author use by making questionnaire. For the analytical method, the author use the multimedia development life cycle method, namely drafting, designing, gathering materials, manufacturing, testing, and distribution. The design of this use adobe flash. The final result of this research is an application system for cultural recognition of the Mandailing tribe using adobe flash.

COMPUTER-BASED LEARNING MEDIA IN ANIMAL RECOGNITION WITH KOREAN LANGUAGE FOR CHILDREN USING UNITY 3D

Rizki Anindya Daulay — 2024-12-15

The rapid advancement of information technology has significantly transformed the field of education, enabling faster and more effective knowledge delivery. One crucial aspect of early childhood education is language acquisition, including foreign languages such as Korean. Inspired by the growing popularity of the Korean Wave (Hallyu), this study aims to develop an interactive computer-based learning media using Unity 3D to teach children about animal names in Korean.

The research follows a System Development Life Cycle (SDLC) methodology, encompassing planning, analysis, design, implementation, and maintenance. Data collection techniques include literature studies, observations, and questionnaires to assess the effectiveness of the developed learning media. The system is designed to engage children through animations, quizzes, and interactive storytelling, making the learning process more engaging and enjoyable.

The implementation consists of animated scenes displaying animal names from A to Z, accompanied by their Korean translations. Two types of evaluation quizzes are included to reinforce learning: identification-based quizzes and fill-in-the-missing-letter quizzes. The final media output is processed using Wondershare Filmora, enhancing the quality of animations and sound integration.

The results indicate that using interactive 3D learning media significantly improves children’s engagement and retention in learning Korean animal names. By combining education with entertainment, this study provides an innovative and effective approach to foreign language acquisition in early childhood.
